JOSEPH EDWARD BLANDING, OF NEW LONDON, CONNECTICUT, ASSIGNOR OF NINE-TWENTIETHS T0 IDA FRANCES WATER Application filed November To all whomit may concern:

Be it known that I, JOSEPH EDWARD BLANDING, a citizen of the UnitedStates, residing at New London, in the county of New London and State ofConnecticut, have invented a new and useful Water Heater, of which thefollowing is a specification.

This invention relates to water heaters, and more particularly to Waterheaters wherein electric energy is employed as the heating medium.

Another object of the invention is to provide a water heater of theinstantaneous type wherein the water will be heated on its passage fromthe water supply, to the spigot or discharge pipe.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings: F igure 1 1s a front elevatlonal view of aheater constructed in accordance with the present invention, the coverplate thereof being removed.

Figure 2 1s a sectional view taken on line 52-2 of Figure 1.

Figure 3 is a longitudinal sectional view through the heater.

Referring to the drawings in detail, the reference character 5designates the .casing of the water heater which is provided with alining 6, formed of asbestos or the like material to confine the heatfrom the resistance coil to be hereinafter more fully described, withinthe casing.

A water inlet pipe is indicated at 7 and has connection with the head 8as through the union 9, which is held to the head 8 as by means of thecollar 10. The head 8 is provided with a recessed portion 11 toaccommodate the upper end of the pipe 12, while the lower end of thepipe 12 is disposed in the recessed portion 13 forming a part of thehead 14. The head 14: is in communciation with the pipe 15, as throughthe lpipe l6 and union 17, which union 17 is also eld to the headassociated therewith by the collar 18.

indicated at 21 is positioned on the pipe 12 and supports the resistancecoil .22 which extends throughout the length of the core 21. As shown,the resistance coil is in circuit with a suitable source of electricsupply to the wires 23 and 24 at the upper end thereof, while the lowerend of the coil'is in circuit with the wire 25 forming the negative 1 ofthe circuit. I

Disposed within the heads 8 and 1 1, and communicating with the interiorof the casing 5, isa pipe 26 through which air may pass as it becomesheated to heat the water passing through the pipe 12. It might befurther stated that the wires that control the electric circuit may becontrolled by any suitable form of switch to cause the electric currentto pass through the resistance coil 22, heating the interior of thecasing as well as the pipe 12.

As the water flows through the pipe 7, and coil 19, it will be seen thatthe same is heated by the electric current passing through theresistance coil 22.

Having thus described the invention, what is claimed as new is In awater heater, acasing, a pipe supported within the casing, a pipehousing the first mentioned pipe and spaced therefrom to provide apassageway, a. water supply pipe leading into the casing and including acoiled portion, said coiled portion being disposed about the firstmentioned pipes and arranged in spaced relation therewith, one end ofthe coiled portion extending downwardly and having communication at theupper end and providing an exhaust for the passageway, and an electricheating coil positioned around the pipes and disposed within the coil toheat fluid passing therethrough. I

In testimony that I claim the foregoing as my own, I have hereto'aflixed my signature in the presence of two witnesses.
